ROBERT S. BOLGER, OI RICHMOND HILL, NEW YORK.

Application filed J'uly 14,

To all whom it may concem:

Be it known that I, ROBERT S. Bonenn, a citizen of the United States, residing at Richmond Hill. in the county of Queens and State of New York, have invented new and useful Improvements in Paper Barrels and Methods of Manufacturing the Same, of which the following'is a specification.

- My invention relates to bilged barrels and the method of manufacturing or producing the same. The object of my inven tion is to produce a barrel of bil ed forma tion, or in other words a barre the ends of which are of less diameter than the medial portion thereof and the body wall of which is composed of stri s of sheet material assembled in such re ation to each other and connected in such form a commercially practical, strong and imperforate barrel adapted for the storage and shipment of produce in general.

Another object in view is to produce such a barrel economically both as regards the material used and the class of labor required, to the end that the barrels may be placed on the market at less cost than the type of barrel now incommon use, requiring staves or hoops.

Another object in view' is to produce a barrel head of cheap and eflicient construction having the requisite factors of strength and lightness for the amount of material used; also to provide a-cheap and practical means for securing such head in the barrel body.

The invention consists in the barrel construction and method of production of the same herein fully described, illustrated and claimed.

The barrel ody is made up ofstrips 1 of sheet material, preferabl consisting of dry, finished paper of suit of modified forma ab density or hard ness to produce a tough and. commercially and united together as hereinafter explained. In this first step of production, as

long a tube (hollow cylinder) as practicable is made and cut in sections each of suitable length to form one barrel body, such length being greater than the length of completed article 'in order to allow for longitudinal contraction of the tube while undergoing the bilging operation hereafter described.

The strips 1 are preferably assembled by a suitable winding machine so that they will extend spirally with' respect to the major axis of-the barrel tube as shown in Figs. 1 and '2 as such method results in a stronger barrel wall. The strips 1 may however extend longitudinally of the barrel body wall as shown in Figs. 5 and 6. In both instances an imperforate main barrel body wall is obtained. The body-forming strips 1 are furthermore assembled with their lateral portions overlapping each other as shown in Figs. 1 to 8, both inclusive, and are united together in such relation by a suitable adhesive. A slowly drying adhesive is preferably used for such purpose to allow ample time for the bilging operation which follows.

The bilging of the barrel tube may be per-.

formed on a machine such as is illustrated in Figs. 9 to. 14, both inclusive, to distort thebarrel'tube shown in Fig. 1, for example, into bilged formation as shown, for example, in Fig. 2. The achine shown, comprises a base A, forming a support for outer and inner forms B and C between which the wall of the barrel tube is confined during the bilging operation. The outer. form is of sectional construction and embodies 'separa-' ble halves connected at the bottom by one or more hinge pins 1) in order that the sections of the form B may be opened or moved apart as shown in Fig. 14 to permit the finished barrel body to be removed from the machine. The sections of form B are secured together at their free edges by any suitable clamping or fastening'means indicated at E. The internal shape of the sections of the form-B corresponds with the bilged external shape of the finished barrel body as shown in Figs. 9 and 11. At one end of the machine there is a fixed stop or annular abutment F preferably consisting of an integral part of the machine frame or base A. During the bilgi'ng operation, one end of the barrel tube rests against said fixed stop, the position of said tube being thus inlet connection or pipe I in the head J thereof, the same being controlled by a valve or stop cock K.

The core member G at the ends thereof has annular flanges L forming spaced seats for the end portions of a resilient flexible sleeve or tube M constituting the inner form, proper. One end of said sleeve or tube is hold between the fixed stop F and the adj acent flange L of the member G. The other end ofsaid sleeve or tube M may extend beyond the other flange L and be held against the head N at that end of the member G and a clamp O in the form of a disk secured to said head by fastening means P. Normally the sleeve or tube M assumes a true cylindrical condition as shown in Figs. 9 and 13, but is adapted to assume the bilged shape of Fig. 11 when fluid (air or liquid) is admitted to the fluid pressure chamber formed within and by the fixed and resilient members C and M of the core or inner form G.

in Figs. 1 and 5 is placed over the free end of the inner form G and over the expansible sleeve or tube M, as shown in Fig. 9. The sections of the outer form B are then closed and fastened as in Fig. 10. Valve K is then opened .and the fluid under pressure fills the fluid pressure chamber passing through the openings H, expanding the sleeve M and pressing the wall of the barrel tube firmly against the inside wall of the outer form B, the laminations of which are still free to change their relative positions due to the fact that the adhesive is still in a moist or unset condition. The pressure may be maintained until the setting of. the adhesive has reached any desired stage or until it has completely set. The pressure is thenreleased, permitting the sleeve or tube M to reassume its normal condition.

The above described operation is repeated for each barrel body. The operation is the same'on both of the barrel tubes shown in" Figs. 1 and 5, or other forms of tubes to be expanded.

At some time subsequent to the bilging.

operation above described, the inner head retaining rings 8 which have previously been made are placed in position and adhesively or otherwise held in place at the proper dis tances from the 'ends of the barrel. One head is then inserted and an outer head retaining ring 9 is then placed in position and fastened by adhesive or other means to permanently secure said head. The other head and its outer retaining ring will or'die nari-ly be applied bythe consumer. A

The head shown in Figs. 15 and 16 is made up of a number of disks 3 and rings 4 punched out of sheet material such as forcing disks diameter are interposed between said disks,-

four of such rings being used, two of the same internal diameter and two of another internal diameter, smaller spacin disks 6, formed in the same way, are p aced centrally between the disks 3, and other rein- 7 of smaller size than the disks 3' are placed upon the latter. All of said 1 disks and rings are united by an adhesive beveled or 1 tweenthem,

bodies and heads may of course,

8 and 9 respectively are each made or other means.

The inner and outer head retaining rings up of a strip of sheet material, such as paper, wound or wrapped upon itself until the necessary thickness of wall is obtained as in Figs. 15, 18, 24 and 25. Such ring may be given a chamfered shape by using a tapering strip of material as in Fig. 24:. The

laminations are preferably united by an ad-.

hesive.

I Fig. 20 the barrel head embodies outer disli s10 between which are placed larger disks 11, rings 12 being placed between the disks 11 and central spacing disks 13 being also used. In Fig. 21 the head is shown as comprising a single large disk 14, a ring 15 of the same diameter, a spacing ring 16 bea plurality of central spacing disks 17, and disks 18 and 19 of different diameters applied to the ring 15. The ar-- rangement in Fig. 22 is similar to that in Fig. 21, two rings 16 being used instead of the one ring 16 and two disks 19 being used in place of he one disk 19. Three spacing disks 147' are also used instead of the two disks 17. The arrangement shown in Fig. 23 embodies the same elements shown in Figs. 15 and 16 except that the-rings 4' are formed with annular offsets 20 which serve to reinforce or strengthen the outer edge portion of the head and also form the equivalent of. gaskets when confined between the retaining rings Band 9. It is to be understood that a barrel head of any thickness may be built up of disks and rings top-roduce. a strong and lightweight structure.

"Any. space remaining between the barrel head and the retaining rlngs therefor and the inside surface of the main'wall of the barrel-may be filled with any sealing medium to' 'obtain' a tighter package.
